Crypto Mixers: New Rules to Spot Money Laundering

China’s top prosecutor office has proposed a fresh approach to catching money laundering that leverages crypto mixers and privacy coins. The proposal argues that the mere use of these tools can signal illegal intent, enabling courts to treat them as admissible evidence.

Why the Change Matters

• Legal Gap: The anti‑laundering law no longer specifies which crimes trigger a laundering charge, yet the criminal code limits those charges to only seven offenses.
• Current Practice: Most crypto cases fall under a vague rule about hiding criminal profits, leading to inconsistent enforcement.
• Proposed Solution: Broader application of the money‑laundering statute and a “one case, two checks” rule to ensure laundering clues are examined in every major criminal investigation.

Three Key Proposals

1. Trustworthy Public Blockchain Records
   Treat blockchain data as credible evidence when hash values match, granting preliminary validity to on‑chain transactions.

2. Burden of Proof Shift
   Once prosecutors present a transaction chain, the defendant must prove its invalidity.

3. Presumption of Laundering Intent
   Behaviors such as using mixers or selling large amounts of crypto at irregular prices can be presumed to indicate laundering unless the defendant offers a reasonable counter‑argument.

Supporting Measures

• Evidence Collection: New rules for electronic data, clearer authorizations for monitoring and traffic analysis, and privacy safeguards.
• Asset Recovery: A national platform to store, value (using on‑chain data and market prices), and dispose of confiscated crypto through approved channels.

Global Context

• US Parallel: U.S. lawmakers aim to extend know‑your‑customer rules to wallet providers and miners.
• Impact: The Chinese proposal could reshape how courts view privacy‑enhancing crypto tools worldwide.

Statistics Highlighting the Need

• Over $16 billion moved through Chinese laundering networks in 2025—about a fifth of the global total.
• 3,000+ individuals charged in crypto‑related cases last year, underscoring the enforcement challenge.

Conclusion

China’s new framework seeks to tighten the legal net around crypto‑based money laundering by making privacy tools themselves a potential piece of evidence. If adopted, it could set a precedent that ripples across international jurisdictions.
